Description

APARATUS FOR PROTECTION AN AUTOMOBILE FROM THEFT

The present invention relates to an anti-theft device of a vehicle, and more particularly, to an anti-theft device of a vehicle that generates an alarm means and prevents the door from being locked when the ignition key is turned off while the door of the vehicle is open.

In general, the number of doors may vary slightly depending on the type of car, but each door is installed in the driver's seat, the passenger seat, and the rear seat, and in order to check whether each door installed in the car is locked in consideration of the high-speed driving of the car. Each door is equipped with a switch, and if any one of the doors is not locked securely, the switch is turned on and a warning lamp lights on the instrument panel to warn the driver whether the door is open.

In addition, when the door is locked, it is composed of 1st stage locking and 2nd stage locking. In the case of 1st stage locking, the warning lamp is turned on because the door switch is turned on, and the door is not completely locked. There will be some play between the doors.

In addition, the window installed in the door of the vehicle to open and close up and down for internal ventilation, etc. has a manual opening and closing form in which the occupant manually opens and closes the lever to open and close the door window of the vehicle, and the motor rotates by receiving power. There is an automatic opening and closing form to open and close the door window of the vehicle by the rotational force of the vehicle, but the automatic opening and closing form to open and close the door window of the vehicle automatically by the rotational force of the motor in accordance with the development trend of the vehicle in pursuit of the convenience and quality of the occupants. It is a general trend.

The door of a conventional vehicle has been realized by turning on / off a switch provided at one side of the middle or one side of the armrest when the occupant or driver needs to park the vehicle or lock it while driving. At this time, even if the door window of the vehicle is open or closed, the opening / closing device and the door on / off of the door window can be turned on or off even when the window is open because the operation device is independent.

However, the conventional apparatus has no means for detecting whether the window is opened / closed when the door is locked, so that the window of the vehicle that is open when the driver locks the door of the vehicle while the driver is mistaken or accidentally opens the window. The problem is that the vehicle can be stolen because it can open the locked door. In addition, when black dust is blown due to rainy weather or bad weather, the vehicle is introduced into the vehicle through a window, resulting in a messy vehicle.

Accordingly, the present invention provides a vehicle antitheft device that can be provided with window closing detection means at the top of the door, and can lock the door based on the signal detected by the detection means and the ignition key on / off signal. For that purpose.

A second controller 7 which outputs a door driving signal according to the door on / off signal, and an actuator 8 which turns the door on / off according to the door driving signal output from the second controller 7. Said, Each detection sensor (1 to 4) is characterized in that installed on one side of the upper door.

Hereinafter, a preferred embodiment of the anti-theft device for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an anti-theft device of a vehicle according to the present invention, the first detection sensor 1 for detecting the open / closed state of the first window and the open / closed state of the second window for detecting A second detection sensor 2, a third detection sensor 3 for detecting the open / closed state of the third window, a fourth detection sensor 4 for detecting the open / closed state of the fourth window, and a start-up A signal detected from the first to fourth detection sensors 1 to 4 together with a signal to be detected in the on / off state of the key is input and based on the start key on / off signal and the first to fourth detection signals. A first controller 5 for outputting an alarm drive signal and a door lock signal, an alarm means 6 for alarming according to an alarm drive signal output from the first controller 5, and the first controller 5 from the first controller 5; The door lock signal outputted as an input and based on the door on / off signal based on the door lock signal. Comprises a second controller 7 and the second actuator controller (8) for on / off the door according to the door drive signal outputted from the (7) for outputting a drive signal.

The first to fourth detection sensors 1 to 4 are installed at one side of each door upper end.

Referring to the principle of operation of the anti-theft device of the vehicle according to the present invention configured as described above in detail.

First, the detection sensors 1 to 4 for detecting the open / closed state of the windows are respectively installed on one side of the upper end of the door, and the installed detection sensors 1 to 4 detect whether each window is completely closed. . That is, it can be turned on or off only when the window is completely closed. Then, it is detected whether the start key switch of the vehicle is on or off, and each window open / close signal and the start key on / off signal detected from the detection sensors 1 to 4 are transmitted to the first controller 5. Is entered. The first controller 5 outputs an alarm driving signal and a door lock signal based on the input signal. More specifically, any one or more of the signals detected from the detection sensors 1 to 4 when the ignition key is on, that is, when the engine is rotating, is an off signal (a signal indicating that the window is open). ), The first controller 5 outputs only the door lock signal. On the other hand, when the ignition key is in the off door, that is, when the rotation of the engine is stopped, any one or more of the signals detected from the detection sensors 1 to 4 are off signals (signals indicating that the window is open). The first controller 5 outputs only the alarm drive signal. At this time, since the alarm means 6 is activated by the alarm drive signal, the driver or the passenger knows that the window is open. The second controller 7 does not output the door lock signal from the first controller 5, so that the actuator 8 cannot be driven even if an on signal for locking the door is input. That is, if the window is open when the ignition key is off, the door is not locked.

Preferably, the first to fourth detection sensors 1 to 4 install a limit switch that is turned on by being pressed by the window when the window is closed, and the alarm means 6 is not mentioned otherwise. Is preferably used.

In the present embodiment, each signal detected by the first to fourth detection sensors 1 to 4 is input to the first controller 5, respectively, but the present invention is not limited thereto. In other words, each of the signals detected by the first to fourth detection sensors 1 to 4 is used as an input, and an AND gate for outputting according to the signals is used, and the first controller 5 outputs the signal output from the AND gate. Of course, the purpose of the present invention can be realized even if the input to.

In addition, in the present embodiment, the alarm means 6 is operated based on the open / close signal of the window and the on / off signal of the ignition key, and the door lock signal is output to control the on / off of the door. Is not limited to this. That is, the alarm means 6 may be activated if the window is open when the door is locked by inputting the door on / off signal to the first controller 5 as necessary.

As described above, according to the present invention, a sensor for detecting the opening / closing of the window is installed on the upper side of each door, and the alarm is based on the start key on / off signal and the signal detected by the sensor. By operating the means and controlling the on / off of the door, there is an effect of preventing theft of the vehicle by generating an alarm sound when the window is open and preventing the door from being locked.
